Teachers need to be very familiar with the outcome being assessed by the Achievement Standard Earth and Space Science 91189. The achievement criteria and the explanatory notes contain information, definitions, and requirements that are crucial when interpreting the standard and assessing students against it. Context/setting This assessment activity requires students to demonstrate their understanding of the formation of rocks in New Zealand by creating a report, a pamphlet, or a PowerPoint presentation that explains in depth the formation, related to plate tectonics of at least one Sedimentary, Metamorphic and Igneous Rock found in New Zealand. Students should have studied Plate Tectonics and learned about: the plates and their interactions in New Zealand over geological time the significant events in the New Zealand’s geological history the main types of rocks in New Zealand e.g. Torlesse Greywacke, Haast Schists. Conditions This activity will take about 10–15 hours of in and out-of-class time. Students complete the activity individually. Resource requirements Sources of information about the formation of rocks in New Zealand, including books, the Internet, and/or discussion with subject experts are listed below: The following websites will be helpful. http://www.teara.govt.nz/en/geological-exploration/6/2 - plate tectonics. http://www.teara.govt.nz/en/geology-overview/3 - gives overview of formation of New Zealand. http://www.teara.govt.nz/en/1966/geology-land-districts-of-new-zealand/1 - lists basic rock types in each area of New Zealand.

Student instructions Introduction This assessment activity requires you to study the formation of rocks in the Banks Peninsula, Canterbury region of New Zealand and to create a report, a pamphlet, or a PowerPoint presentation that explains how two or more of these rocks have come to be in Banks Peninsula. You will be assessed on the depth and comprehensiveness of your explanation. You will have 10–15 hours of in- and out-of-class time to complete this activity individually. Task Select two or more rocks found in Banks Peninsula. For each rock, create a report, a pamphlet, or a PowerPoint presentation that: identifies the type of rock and where it is found on Banks Peninsula explains how plate tectonics have formed this type of rock explains how rock-cycle processes have formed this type of rock link the plate tectonic and rock cycle processes that have formed this type of rock explain how erosion has shaped landforms (on Banks Peninsula) that are made of this type of rock over time. Your teacher will provide you with a list of resources for this task.

The student has produced a report, pamphlet, or PowerPoint presentation in which they investigate in depth geological processes in a New Zealand locality. The student has produced a report, pamphlet, or PowerPoint presentation in which they investigate comprehensively geological processes in a New Zealand locality. In the report, pamphlet, or PowerPoint presentation, the student: In the report, pamphlet, or PowerPoint presentation, the student: identifies two or more rock types found on Banks Peninsula For example: Early eruptions in cretaceous period were of Rhyolite and Andesite laid down over Greywacke. Rhyolite formed when silica rich magma erupted and cooled down quickly. In the report, pamphlet, or PowerPoint presentation, the student: identifies two or more rock types found on Banks Peninsula For example: Early eruptions in the cretaceous period were of Rhyolite and Andesite laid down over Greywacke. Rhyolite formed when silica rich magma erupted and cooled down quickly. describes plate tectonic processes that formed the rocks on Banks Peninsula For example: Greywacke is very old in Banks Peninsula and was formed by heat and pressure under the earth and uplifted during the Rangitata Orogeny. describes the rock cycle processes that formed the rocks identified on Banks Peninsula For example: Greywacke found on Banks Peninsula was formed by sandstone laid down as sediments off the coast of Gondwana. describes erosion that has shaped current This resource is copyright © Crown 2015 explains plate tectonic processes that formed the rocks identified on Banks Peninsula For example: Rhyolite was erupted from Lyttleton stratovolcano. It was made from high silica content magma that does not have dissolved gas in it. Rhyolite has very small crystals, which are because it has been formed from silica-rich magma erupted from a Rhyolitic volcano and cooled very quickly on the Earth’s surface. explains the rock cycle processes that formed the rocks identified on Banks Peninsula For example: identifies two or more rock types found on Banks Peninsula For example: Early eruptions in cretaceous period were of Rhyolite and Andesite laid down over Greywacke. Rhyolite formed when silica rich magma erupted and cooled down quickly. links plate tectonic and rock cycle processes that have formed the identified rocks found on Banks Peninsula For example: Rhyolite erupts at a low temperature of 800°C and is the most violent type of eruption. This means that Rhyolite is erupted the most violently and quickly out of a volcano (such as Lyttleton) and the resulting surface rock cools down the fastest to have very small crystals. The Rhyolite erupted onto the greywacke base. It has a mineral composition that shows it is made up of partical melting of the mostly quartzofelpathic Torlesse sediments. Torlesse greywackes were formed from sandstone, which can be mined on Page 5 of 6 Internal assessment resource Earth and Space Science 2.3A v2 for Achievement Standard 91189 PAGE FOR TEACHER USE landforms of these rocks on Banks Peninsula For example: The Rhyolite and Andesite deposited on Banks Peninsula indicate that they were deposited by a stratovolcano, which is a very different shape to the shield type shape of Banks Peninsula today. Greywacke was only slightly metamorphosed by heat and pressure, which indicates it was not buried very deep before being uplifted by the Rangitata Orogeny. explains how erosion has shaped current landforms of these rocks on Banks Peninsula For example: The large symmetrical cone shaped volcano has eroded over approximately 80 million years of wind and rain action upon the rocks. This has eroded the cone shape to the low-lying round shape seen today. Banks Peninsula today and is found under the rhyolite, which indicates that it is older than the rhyolite. links erosional processes with the shape of the current landforms on Banks Peninsula For example: The prevailing weather on Banks Peninsula has eroded the stratovolcano shape over time (2-8Ma ago) leaving only exposed Basaltic dykes in places. The overall shape of Banks Peninsula is now a gently rounded, deeply incised shield volcano shape. However, the presence of rhyolite and Andesite on Banks Peninsula indicates a stratovolcano was once present with a classical cone shape at the end of the Cretaceous. Final grades will be decided using professional judgement based on a holistic examination of the evidence provided against the criteria in the Achievement Standard.
